AD GRS
The BOFA AD GRS is a fume and dust extraction system designed for the jewelry industry that recovers and collects precious metals. The metal particles are collected in an easy to remove tray. The AD GRS packs a powerful range of unique features into one compact unit and is a complete solution for the extraction, filtration, and recovery of precious metals. Automatic Flow Control allows the user to preset correct flow rates, for lower noise levels and further protection of both the combined and pre-filters.
Includes Remote Stop/Start
- Enables the extraction unit to be remotely turned On/Off via an external signal.
Includes Filter Change/System Failure Signal
- When the filters become blocked, or the system develops a fault the connection between the Green & White cables will become “Open”. When the extraction system is normally running the connection between the Green & White cables will become “Closed”.
Reverse flow air technology
The reverse flow air technology feature causes a fall in velocity and air direction change. Larger particulate falls out of the air stream into the filters drop out chamber. With less particulate entering the filter media the filter life is significantly increased. Contaminated air entering the drop out chamber is pulled vertically through the filters.
Automatic Flow Control (AFC)
AFC allows the operator to preset correct airflow rates for the specific application, subsequently maintaining this airflow. This generates lower noise levels and ensures further protection of HEPA filter.
HEPA Filter and Advanced Carbon Filter (ACF)
HEPA filter filters 99.997% of particles at 0.3 microns in size. ACF helps enable safer filtering of hazardous fumes. Contaminated air must remain in contact with the carbon bed for a period of time sufficient to ensure that no contaminants or odors are emitted (‘dwell time’). Bofa design considers the balance between airflow rates and the type, depth and surface area of the carbon used to ensure suitability for the contaminants associated with the application and to ensure appropriate dwell times are achieved.
